Problems scanning to CD

[michael_mcdonald1]

I have had my local lab put some of my film on CD. Some can be seen

here

I know that they aren't the greatest shots but there is something I

have noticed on the scanned pictures that aren't in the prints. The

scanned images look pixelated. I don't know if that is the right

word or not but lines are not smooth there are jagged edges.

 

Is there a specific way to scan the film that would get rid of that?

 

Also I have a roll of slide film I would like to have processed is

there a special way I should have that scanned?

 

The attached pic shows what I am talking about. Her neck and face

look jagged.

I just looked at that pic full size and it isn't as bad but there is still a little something on the lines.

The scans are probably not done at a very high resolution, and/or they may be compressing the jpegs quite a bit.

I agree with Les, the "jagged" neck and face are caused by JPEG

artifacting. This is odd because the quality is the highest

possible, although it uses 2x1 chroma subsampling, which is a

pretty silly combination. The picture also looks dark because

it doesn't fill up its histogram. Where did you get the scan?

Did you edit or crop it? Doesn't look like Frontier and the size

is wrong for Agfa d-Lab.2 or Noritsu. We can help you minimize

JPEG problems if we get some answers to those questions.

I had them scanned at my local lab. Lakeside Camera in Louisiana.

It wasn't edited or cropped. I have asked one of the people that work there if there was anything they could do differently but was told I needed to talk to someone else. I don't know anything about scanning so I was hoping someone could tell me what to tell them to do.

Les, according to the "jpegdump" program, JPEG quality is already 100

(highest possible). I suspect it was recoded from a lower JPEG

quality level, or something extra silly like that. Michael, ask the

lab if they can provide TIFF scans. No reason why not -- 36 full-res

scans and thumbnails will easily fit on CDR.

The <B>jpegdump</B> program was written by Allan Hessenflow. C source

and Win32 executable are available on the web. I've got version 1.14

-- please let me know if I should upgrade. There is another program

called jpegdump that (I believe) recovers damaged digicam files, by

Kurt Stege.
